JOHN A. PURA, OF GONZALES, CALIFORNIA.

MOWING-MACI-IINE.

To all whom it may concern:

Be it known that I, JOHN A. PURA, a citizen of the United States,residing at Gonzales, in the county of Monterey and State of California,have invented a new and useful MowingMachine, of which the following isa specification.

This invention has relation to mowers and it consists in the novelconstruction and arrangement of its parts as hereinafter shown anddescribed.

The object of the invention is to provide a mower of simple constructionand arrangement of parts and which comprises a frame in which isjournaled an axle in the usual manner, tract-ion wheels are mounted atthe ends of the said axle and the axle is operatively connected with theforwardly and downwardly disposed shaft which in turn is operativelyconnected with the sickle bar of the cutting apparatus. The parts are sogeared as to cause the sickle bar to reciprocate at a relatively fastrate of speed.

A further object of the invention is to provide a reel structure adaptedto be applied to the finger bar of the cutting apparatus. The said reelstructure includes standards, upon which are adjustably mounted journalbearings- A reel shaft is journaled in the said bearings and isoperatively connected with the main shaft of the mower 4. A braceextends from the main shaft of the mower to one of the said standards.By providing a mower with a reel structure as indicated, the mower maybe used for cutting short grain and can also be used to advantage forcutting grass in windy weather, or when the grass is in a tangled. stateas the reel will materially assist in positioning and supporting thegrain or grass at the time it is operated upon by the knives carried bythe sickle bar.

In the accompanying drawings,Fig"ure 1 is a top plan view of the mower.Fig. 2 is a side elevation of the same. Fig. 3 is a rear elevation ofthe cutting apparatus with the reel structure applied thereto. Fig. 4 isa side elevation of a portion of the reel structure. Fig. 5 is atransverse sectional view through one of the standards of the reelstructure.

As illustrated in the accompanying drawings, the mower includes a frame1 to which is attached the rear end of a tongue 2 in the usual manner.An axle shaft 3 is journaled for rotation in the frame 1 and trac-Specification of Letters Patent.

tion wheels 4 are mounted upon the end portions of the said axle shaftin the usual manner.

A housing 5 is formed upon the frame 1 and contains a train of gearwheels 6 which operatively connect the axle shaft 3 with a shaft 7 whichin turn is j ournaled in a forwardly and downwardly projecting arm 8which forms a portion of the frame 1. A disk 9 is fixed to the portionof the shaft 7 and a cutting apparatus 10 is pivotally connected withthe frame 1 and its extensions in the usual manner. A pitman bar 11operatively connects the disk 9 with the sickle bar 12 of the cuttingapparatus in the usual manner. The parts are so proportioned and gearedthat the sickle bar 12 will reciprocate at a relatively high rate ofspeed.

Standards 13 are mounted upon the end portions of the finger bar 14 ofthe cutting apparatus 10 and at their upper portions the said standards13 are provided with vertically disposed elongated slots 15. Bearings 16are adjustably mounted in the standards 13 and each bearing comprisesbinary plates 17 having registering shaft openings 18 and oppositelydisposed webs 19 adapted to enter the slots in the standards 13. Theplates 17 are held together by clamp bolts 20 which also pass throughthe slots 15 in the standards 13. By this arrangement it will be seenthat by loosening the bolts 20 that the bearings 16 may be adjustedalong the standards 13, and when in proper position can be secured bytightening the said bolts 20.

A reel shaft 21 is j ournaled at its end portion in the bearings 16 anda sprocket wheel 22 is fixed to the inner end of the said reel shaft 21.Disks 23 are fixed to the reel shaft at points within the bearings 16and radially disposed arms 24 are carried by the said disks 23. Theouter ends of the arms 24 upon one disk 23 are connected with the outerends of the arm 24 upon the other disk by the battens 25. A sprocketwheel 26 is fixed to the end of the axle shaft 3 at a point beyond theouter side of the traction wheel 4 adjacent the cutting apparatus 10 anda sprocket chain 27 passes around the sprocket wheels 26 and 22. Thechain 27 is sufliciently loose to permit of the vertical adjustment ofthe bearings 16 as above described. An arm 28 is pivotally connected atits forward end with the inner standard 13 and at its rear end isprovided with a bearing 29 which snugly receives the projecting end ofthe axle shaft 3. Preferably a swiveled joint 30 is provided between therear end of the arm 28 and the bearing 29. The arm 28 and its attachmentserves as means for bracing the reel structure and for holding the reelin proper position to cause the material being operated upon to assumeerect positions as it is engaged by the knives upon the sickle bar andto pass promptly over the cutting apparatus after it has been severed.By providing the standard 13 with the elongated slots 15 and bearings 16adjustably mounted upon the Said standards along the said slots, thereel-proper of which the parts 21, 23, 2% and are the principal members,may be adjusted vertically in order to operate upon grain or grass ofdififerent heights. It will also be seen that while the reel structureis braced in its position upon the cutting apparatus there is sutlicientflexibility or play at the oints of the parts which connect the reelstructure with the axle shat't of the motor to permit of limitedvertical movement on the parts of the cutting apparatus and a certainamount of vertical swing of the same.

Having described my invention what I claim as new and desire to secureby Letters Patent is A mower including an axle shaft and a pivotedcutting apparatus, standards mounted upon the cutting apparatus, a reeljournaled for rotation upon the standards, means operatively connectingthe reel with the axle shaft, and a swiveled brace rod connected one endwith one of the standards and at its other end with the axle shaft.

In testimony that I claim the foregoing as my own, I have hereto atlixedmy signature in the presence of two witnesses JOHN A. PUB-A.
